While Mikki and James were away, I invited Patricia, or Pat as she preferred to be called, my sister, to visit. It was her first time staying with us. If you've read the first two stories of "Our Sexual Adventure," you might remember her as the one who hosted the parties where I tried to talk to Bob, and another time when I flashed my boobs at him, and we started dating. She also attended my wedding in Plymouth with my dad and stepmum.

Growing up, we were quite close, though she was three years older than me, making her twenty-four when she visited. Like me, she married at seventeen, but unlike me, she was pregnant at the time. She had a seven-year-old son and a four-year-old daughter, whom she left at home with her husband, whom she referred to as "the slob."

I always admired her; she was everything I wasn't back then—outgoing, carefree, flirty—and I assumed she was having fantastic sex.

She was a bit taller than I was, sharing the same hair and eye color but with a more curvaceous figure and exquisitely large breasts. While Mikki had ample curves, Pat’s were on another level, reminding me of the time Bobbie had seen them at the party she hosted back in Yorkshire. We always made a point to visit her whenever we returned. When she was with that slob, she was subdued; on her own, however, she was witty and effervescent.

On Saturday, I met her at the train station, and the three of us enjoyed a night of eating, drinking, and plenty of laughter. She was sleeping in Mikki’s room as they were all away. The next day, I invited her to go out with me, casually mentioning that Bob frequented the club to watch strippers, and sometimes Mikki and I would join him. She readily agreed, thinking it would be fun and a chance to rub it in the face of that slob, who was a regular at strip bars.

That Sunday afternoon turned out to be fantastic. There were three strippers: the familiar redhead we’d seen before and two gorgeous blondes with long hair. The blondes performed a second act together, which I found incredibly arousing despite being purely sensual. Pat admitted she loved it, much more appealing than those cheap, tacky shows her husband used to take her to, where his buddies would ogle her breasts and make lewd remarks.

For those who’ve followed my stories, we had Chinese takeout for dinner paired with a few glasses of wine. The following day, Bob left for the barracks while I had the day off, so Pat and I spent the day together. We went shopping like old times; I took her to my favorite lingerie store, where we picked out some beautiful sets for when Mikki and James returned. Pat indulged herself, declaring that everything she picked was absolutely perfect.

After a relaxing lunch at a pub, we headed home on a sunny day and opened a bottle of wine. I pulled out a pair of bikini bottoms and handed them to Pat, joking that I didn’t have a top that could come anywhere near her. She donned the bottoms with a sleeveless T-shirt, while I wore just my bottoms and a robe. Soon after, sitting in the garden, I removed the robe and sat topless. After a few wines, Pat inquired whether anyone would mind me being exposed at the top. I explained that Mikki and I often sunbathe nude without any objections, and it even gives the bin men a bit of a thrill. Taking off her top as well, she remarked how much I had changed from when I used to live with her; back then, it was always Pat who would flash her breasts. She added that the change was for the better, and she was pleased I’d become more relaxed.

With the second bottle of wine poured Pat asked about Mikki, knowing about my fondness for women. So, I told her everything about the four of us and the various escapades we shared. For the first time in my life, I truly shocked my older sister. Then, she began to share her own stories, from our childhood, when she used to tell me about the boys she'd kissed and how they’d handled her breasts, and even when she started experimenting with feeling their cocks. What she revealed now deeply shocked and upset me.

Before meeting her husband, she had sex with three boys. Technically, it was only two since the first one finished before any actual intercourse, coming all over her pussy. The other two did manage to proceed, but one finished after just a few strokes, leaving her disappointed each time. Then she met her husband, who at least lasted longer. They always had sex in the missionary position, and after marriage, their routine was the same: lights out, lift her nightdress, have intercourse, and then he would roll over and fall asleep snoring.

She confided in me that she had never experienced an orgasm during penetrative sex and would satisfy herself after he fell asleep. When I asked about oral sex, she admitted she had tried it, but he pushed her away, calling it dirty, and refused to reciprocate. I felt terrible for her, but the worst part was that they hadn't been intimate for over a year, and even when they did, it was maybe once a month.

She had caught him cheating multiple times, but he always managed to convince her to stay by bringing up their children. When I asked if she had ever cheated, she said she was tempted but hadn't. Pouring two more glasses of wine, I looked at Pat and suggested, "I'm going to ask Bobbie to fuck you properly and make you scream."

She laughed, thinking I was joking, but when I asked if she would genuinely like that, she admitted she would, and that it would serve her husband right. Still, she didn't think I would let it happen. I told her I loved her and wanted her to experience what a good lover could offer, mentioning that Bobbie was indeed a good lover. I also confessed that while living here, I had been with four other men, and Bobbie had been with three other women, so being with her would balance things out. Taking a large gulp of wine, she looked at me and realized I was serious. I told her I enjoyed watching Bobbie with other women and couldn’t think of anyone I’d rather see him with than her. She became shy and asked if she could just be in the room with him for it. I said that was fine but added if it happened again, I wanted to be there. We agreed it was a deal.

That evening, when I spoke to Bob, he was more than willing to help out. I teased him about getting to touch those large breasts he had seen. I had taken the week off work, so the next day we both sunbathed, this time without any clothes. I glanced at her untrimmed pubic hair and suggested she do something about it. She mentioned she used to trim it but hadn't bothered in over a year since no one had seen it.

I pointed to my neatly trimmed area and suggested she take a shower and groom hers similarly, as she was going to get fucked properly that night. She eagerly asked if Bob had agreed, and I confirmed that he was looking forward to it. I then inquired about the size of her husband's penis, and she confessed that it was rather large. She demonstrated with her fingers, estimating it to be about four or five inches. When she asked if Bob was that big, I assured her she was in for a pleasant surprise. Curious about his size, she was told she'd find out soon enough. I advised her to go to her room after dinner, put on her new lingerie, and I handed her a pair of hold-ups. She was to lie on the bed with the lights on, and I would send her surprise to her. After finishing her wine, she went to the bathroom to prepare. I informed her that a new razor and scissors were available in the cabinet.

After dinner, while Bob and I tidied up, Pat excused herself to get ready. I sent Bobbie off to our bedroom, and as I peeked into Mikki’s room, I saw Pat lying on the bed in hold-ups, a bra, and panties that were surprisingly sheer—something I hadn’t noticed back at the shop. I told her she looked stunning and encouraged her to relax and enjoy the moment. Then, returning to my own bedroom, I instructed Bobbie to change into some loose shorts.

I took a moment to offer Bobbie a few tips, mentioning that it had been a while for Pat and that whatever else transpired, he should go down on her, giving her pussy a good licking, as I knew that was what she desired. With a slight tug on his shorts, I took Bob’s cock in my mouth, kissing its tip and urging it to revel in the sensation. I then kissed Bob and reminded him not to return until Pat was completely satisfied and had experienced two orgasms.

After Bobbie left, I undressed and reached for my little vibrating bullet from the drawer before reclining with a glass of wine. The quiet mood was interrupted only by a loud moan. As I listened to the sounds of their play, I began to finger myself while using the bullet to stimulate my clit. After my second, overwhelming climax, I set the bullet aside, sipped some more wine, and drifted off to sleep.

I’m not sure how long I slept, but when I woke up, I found Bob already in bed, naked and carrying the scent of a fresh shower. I kissed him and asked if Pat was alright. He replied that she was soundly asleep with a smile on her face. I inquired whether he had followed my instructions, and he confirmed that she had come three times. I kissed him again, calling him my stud spooning, before drifting back to sleep.

The next morning, Pat entered our bedroom wearing a tiny nighty and sporting a huge grin, carrying coffee and toast. She left us to enjoy breakfast in bed, and then Bob headed off to work. Later, Pat and I went for a walk, pausing for a drink and a sandwich. When we returned home, we put on bikini bottoms and lounged in the garden. Sensing that Pat was eager to talk, I listened as the first words to escape her were, “Can we do it again?”

Smiling, I replied, “You know exactly what that means.” She admitted that she didn’t care, I would be there regardless, she just had to experience it once more. I grinned and said, “Alright then, spill the beans.”

She confided that while she wasn’t a virgin last night, it was her first time experiencing true sexual fulfilment, climaxing during penetration and from oral sex. I asked if she performed oral sex on him, and she said she tried but felt uncertain about her technique, asking if I could guide her.

I asked her where he had cum, and she told me the first time was inside her, then on her breast, another first, and the last time inside her again. She admitted she could actually feel his cum inside her when he came, something she'd never experienced with her husband. I suggested it might be because he was deeper than what she was used to.

She then shared her embarrassment about boasting to me about her husband's size, only to see Bob reveal an impressively large cock. I confessed I hadn't mentioned it before, but I had measured it at just over eight and a quarter inches and very hard. Once she got accustomed to it, she loved the sensation.

I inquired about her orgasms; turns out, she had come five times, twice from oral sex, once during their first intercourse, and twice during their second round. She kissed me on the cheek, thanking me for encouraging her to experience this.

Bobbie found us sunbathing nude in the garden. I greeted him with a kiss and teased that we were giving him a preview of what awaited him later, two eager pussies. We enjoyed pizza and wine before the three of us retired to the bedroom.

Bobbie performed oral sex on both of us and then I demonstrated my technique on him for Pat. She tried it and felt more confident. I then guided Pat into a new position, helping her straddle Bobbie and ease him into her. After they both climaxed, I cleaned him with my mouth getting him hard again. I got on my hands and knees, inviting Bobbie to take me from behind, a position Pat said she had tried the night before.

Eventually, Pat returned to Mikki's room, and I fell asleep in Bob's arms.

Thursday was dull with no sun, so Pat and I decided to stay in and catch up on some housework, followed by a long conversation. I shared with her about the two swaps we had and spoke in detail about Katy and Tom. I mentioned how she spanked me after observing Bobbie do it. I also recounted all the details of my wedding night and honeymoon, beyond just the usual highlights. She was genuinely taken aback but expressed a wish that she had experienced similar things.

Pat then confided in me that this visit had been an eye-opener and had helped her decide on her future. She had resolved to leave her husband, even if it meant being alone with her two children. This was the first time she had spent any significant time away from him, and without his constant presence, she realized he would never change, and she would remain unhappy.

I asked her about her feelings towards sex now, and she simply replied, "Free!"

I encouraged her to make the most of her remaining two nights and enjoy as much intimacy as she desired. I suggested she stay with us tonight rather than going to another room. I also proposed that she try something new, which made her nervous. I suggested that when she sucked Bobbie, she should let him finish in her mouth and swallow.

She was apprehensive and said she couldn't do it, but I shared my experience. Wendy had encouraged me to try it, and though I was hesitant at first, I ended up enjoying it and did it regularly with Bobbie, Tom, and James. I explained that they each tasted different but delightful. She agreed to think about it, and I advised her that trying was the only way to know, and if she didn't like it, she didn't have to do it again.

I reminded her of all the new experiences she had tried and enjoyed during her visit and noted that it would be better to experiment here with Bobbie than risk an awkward situation with a stranger. Pat agreed to give it a try before heading home.

When Bobbie arrived home, he expressed his disappointment that the weather wasn't better, as he had hoped to see us both naked in the garden. I reassured him that later tonight, he would have us both naked, hot, and eager for him. I also asked him to focus more on Pat over the next two nights.

Later, when we went to bed, Bobbie had fucked Pat twice, turning his attention to me in between. Pat and I took turns sucking his cock, keeping him hard. After coming in Pat for the second time, he went down on Pat cleaning all his mess, bringing her to her fifth orgasm of the night, all with Pat looking at me in amazement.

We fell asleep with Bobbie in the middle. I awoke to find Pat giving Bobbie a blow job; her skills had significantly improved over the week. Soon, she had him on the edge of climax, with Bobbie warning her that he was about to cum. Instead of stopping, she kept him in her mouth. I could see his cock pulsing, and with a moan, he released into her mouth. I watched as her throat tightened while she swallowed. After taking a breath, she went straight back to pleasing him orally.

Smiling, she looked at me and said, "Okay, you were right again."

Friday I managed to get Pat an appointment with the solicitor that had sorted Mikki’s divorce, I paid for the appointment to help her knowing she needed good advice.

As I sat and listened to Pat tell her all the details of her marriage his affairs and the way he treated her I was even more shocked. The solicitor gave her lots of advice, telling her to try and catch him in the act and if possible get photographic evidence. Finally she told her to instruct a good solisitor who specialised in divorce and family matters, as it would pay for itself in the future.

At home Pat asked if she could stay an extra night of course I’d like that, she let her husband know telling him what time the train would arrive. He told her he was busy and to get her Dad to pick her up or get a taxi. I was so pleased she’d decided to leave him. I told Pat she would have to sleep with us as Mikki and James were coming back late on Saturday.

Friday night Bobbie made love to both of us swapping between us, coming twice in Pat's pussy and once in her mouth, as I finger fucked myself.

Saturday we all went out had a pub lunch then went home going to bed early as this would be Pats last night. Whilst Pat was giving Bobbie a blowjob I heard a key in the front door and Mikki whispering to keep quiet. I was pleased they were home safe. Bobbie and Pat were too busy to hear them.

Pat was in a particularly playful mood on her final night with us. Under the covers, she was giving Bobbie an enthusiastic blowjob while I listened to her delighted moans. Suddenly, the door burst open and as I looked up, I saw a naked Mikki rushing toward the bed. Before I could intervene, she had pulled back the covers, shouting “Surprise!”, though it turned out that Mikki was the one who truly got surprised when she noticed Bobbie’s cock buried in my sister’s mouth.

I introduced Mikki to my sister, and Pat managed a quick “hi” before immediately returning to Bobbie, as if using him for protection. Mikki apologized, explaining that since her bed was empty, she had assumed Pat had already left. Both Mikki and I couldn’t help but laugh at the unexpected turn of events. Mortified, Pat fretted about what Mikki would think of her, but I reassured her not to worry, urging her to let Bobbie have his way. Still, Pat insisted she couldn’t go through with it, especially with the others so close by. As I fondled Bobbie’s hard cock, I teased Pat that she was really giving up her final chance to experience being filled. Her tension eased when she began to hear Mikki’s moans from next door.

The next morning, once awake, I again went down on Bobbie before telling them to enjoy their last shag, leaving Pat some time alone to savour her moment. Later, when I went to get coffee, I found Mikki seated and feeding Oliver. She commented on how attractive my sister looked and asked for some details about what had happened; I offered a brief explanation.

After Pat had showered, I handed her a pair of bikini bottoms and mentioned that Mikki was outside. I slipped into my own pair of bottoms and my robe and stepped out. There, Mikki lay naked on a lounger; catching Pat’s eye, she nodded, and the two of us disrobed to join her. About an hour later, Bobbie and James emerged to say goodbye as they prepared to head off to the club, I even caught James giving my sister a lingering look.

Before long, I announced that it was time to get Pat ready for the train station. Once everyone was dressed again, Mikki carefully placed Oliver in the car seat and climbed in beside him while Pat sat in the front next to me. With plenty of time to spare, we stopped at a café for lunch. As we stood on the platform waiting, Mikki bid Pat farewell with one long, passionate kiss before taking Oliver over to inspect a stall. I gave Pat a quick, sisterly peck, and she then asked me if it always felt that good kissing Mikki; I replied that it truly did. She thanked me sincerely for everything—for helping her decide on her future and for sharing Bobbie, showing her what she had been missing.

As she waved from the train window, I blew her a kiss. Later, when I found Mikki, she asked why I had never mentioned just how beautiful my sister was. I mused that if Pat had stayed for just one or two more nights, she might have ended up in Mikki’s bed, completely seduced.

That week-long visit only strengthened the already strong bond between the two sisters. Though Pat and I never recreated the same experiences, we often reminisced fondly about her stay. For those curious about what happened when Pat returned home, her marriage, and her sex life, I'll elaborate in a separate story. I'm planning a side narrative titled "The Wedding Party," which will delve into the lives of everyone in my wedding party, including my sister Pat. As expected, there will be a few surprises, and I'll make sure it aligns with the timeline of our main adventure.
